FOREWORD 


BUILDING codes throughout the country are constantly 
being improved. Regulations covering the erection of buildings 
are continually becoming more stringent. 

This means that building units must keep pace—they must 
be continually improved in quality. This applies to concrete 
building units as well as any other. 

Rapid growth of the concrete products industry has brought 
success to those who turn out high grade products. 

But knowing how to make good products and using the 
best materials will not produce them. The best equipment 
obtainable is also necessary. 

To improve the quality of the concrete product, the ma- 
chinery must be first improved. In response to this constant 
demand, the Anchor Concrete Machinery Company has bent 
every effort to make each machine in its complete and varied 
line better than heretofore. 

For years the old Anchor Line has stood for reliable quality 
in concrete machinery. Neither time nor pains have been 
spared to make it better. Constant experiments have led to 
many improvements in design and construction. The result 
is shown in the following pages—the best concrete machinery 
on the market at reasonable cost.

Let’s Have More Knowledge and Better Manufacturing 


By Harvey WHIPPLE 


Secretary, American Concrete Institute, and 
Editor of ‘‘Concrete’? Magazine 


INCE 1920 very rapid progress has 

been made in establishing concrete 

S blocks, tiles and bricks in the field of 

masonry building units. Only a por- 

tion of the credit for this belongs to 

concrete building unit manufacturers. The more ex- 

tensive use of their products has been very largely 

an economic development from two causes: first, 

the very active housebuilding activity of the 

country; second, the scarcity and higher cost of 

burned clay units, bricks and tiles, due to the 

scarcity and high price of fuel. Rail congestion and 

higher freight rates have had an effect in the same 

direction in some localities, because in many, 

probably most districts, concrete building units 
represent local enterprise. 

Manufacturers of machinery have been close 
on the heels of this changed situation with equip- 
ment designed for much larger production. Such 
machinery costs much more money than the hand 
outfits with which the industry started. This has 
had its influence in reducing the number of small 
operators with limited capital, and by the same 
cause, coupled with the greater demand for 
masonry materials, has tempted into the concrete 
products manufacturing field a type of investor 
who was not interested in the hazards of the 
business when it was overcrowded by small 
back yard competitors. Concrete building unit 
production has taken on the dignity of a real 
manufacturing enterprise. 


Proaress Was SLOW 


State the reverse of these forward conditions 
and you have an explanation of the comparatively 
slow progress of the concrete building unit manu- 
facturing field in the preceding decade. Good 
concrete blocks have been made by some producers 
for thirty years and in a few localities these units 


came very early to occupy a place of importance. 
Sometimes this has been due to the push and 
personality of the manufacturer; sometimes to the 
knack or judgment of some builder in using 
the products so that they sold themselves from 
the very first; sometimes a purely local economic 
condition in the building material field operated 
in favor of the unit, and in some cases building 
authorities were prompt in the acceptance of a 
building unit which promised an advantage. 

Generally speaking, the concrete building unit 
business just “dubbed along” for years. It made a 
fair living for many none-too-ambitious producers; 
sometimes only wages. But always more and more 
were going into the block business, tempted by 
the exceptional example of the few who had made 
a success and lured also by the easy terms upon 
which a small amount of manufacturing equip- 
ment could be obtained. Of the fine points of good 
concrete many of these early block makers knew 
very little and less perhaps of those manufacturing 
fundamentals of productive efficiency upon which 
any really worth while success must depend. 


Bap Biocks MADE 


Making concrete seems to be so easy and 
making good concrete was a thing we then knew 
so little about, either from a scientific or an artistic 
standpoint, it probably should have been no sur- 
prising result that a great many very bad concrete 
blocks were made, sold and used. Not only were 
they poor units from almost any viewpoint but 
they were badly used, and the result was a back- 
lash of disapproval from almost all discriminating 
builders. This left the field only to cheap business. 
A cheap business does not attract good investors. 
It is easy to cheat in making concrete block, 
but zt doesn’t pay. With the small production 
equipment in use, the small market for a new and

questionable unit, with no unusual economic 
pressure to force its greater use, with only a few 
men in the business with a clear vision of its 
greater possibilities, the concrete building unit 
business, except in a few notable instances, 
just held its own, sometimes scarcely that 
much, until there emerged from a variety of 
causes a better combination of developing cir- 
cumstances. 


LEARNED More Apout It 


We have learned, first of all, more about making 
concrete. We have learned that no general state- 
ment can be made that concrete blocks, tiles and 
bricks are good building units or that they are not 
good building units. We know that their value 
depends on precisely what they are made of and 
how, and also upon how they are used after they 
are made. One concrete block house which is 
damp or cold or unsightly can remove many good 
business prospects. You do not find many people 
who are afraid to build with clay bricks, because 
clay bricks have given satisfactory service for some 
thousands of years. A cold house, a damp house, 
an unsightly house built of clay bricks excites no 
one, prejudices few. Why? Because clay bricks 
have established traditions and when something 
goes wrong it is customary to look for the cause 
in the way the building was erected rather than in 
the way the bricks were made. Clay bricks were 
here before we had any building laws or methods 
of test. People are accustomed to the idea. 
Gradually, very rapidly in fact of late, due to the 
fast moving age in which we live, concrete has 
been establishing traditions of its own and is 
making history. Elaborate series of comparative 
tests show us at length very convincingly that 
concrete units properly made are a very superior 
building material. It is no longer unreasonable 
even to general builders to suppose that concrete, 
with so many different kinds of successes to its 
credit, should be used satisfactorily for building 
units. That is the public frame of mind. Then the 
economic urgency. That is the most convincing 
thing. With more knowledge of concrete, a greater 
public acceptance of concrete, a better technical 


understanding of how to make it and use it— 
along with these have been developed a tireless 
market for more building materials and _ the 
urgency placed upon the producers of machinery 
to give us the equipment with which to make good 
building units and make them fast, fast enough 
so that they are not cheapened in the old way, in 
quality, but only in price. That is how it comes 
about that hundreds of millions of the old tradi- 
tional clay building units are being displaced by 
concrete building units. 


Mucus To BE Done YET 


We still have a great deal to accomplish in the 
concrete building unit field. 

We must develop more uses, better uses and a 
more nearly standardized product. - 

No one should’ be in the business of manu- 
facturing concrete building units until he has 
learned, first of all, the fundamentals of good 
concrete. 

It is possible for a well informed architect or 
builder conscientiously to recommend the use of 
concrete blocks only when he knows whose make 
of blocks, unless the recommendation is coupled up 
with certain qualifications as to what quality of 
blocks to use and how to use them. That plainly 
indicates that we need more general adherence to 
standards of quality. So first of all the manufac- 
turer himself should know more about what 
good concrete is, the fundamentals that remain 
the same with respect to concrete, whether the 
thing being made is a building block, a Panama 
Canal or a Fountain of Time. 

He should begin his education, if he is new to 
“the concrete business,” by putting out of his 
mind the idea that concrete is “mud,” as it is 
often referred to on the job. Concrete—good 
concrete—is an engineering product, all bound 
‘round by chemical and physical laws which can’t 
be successfully violated. The day has passed when 
the manufacturer of concrete building units can 
scorn the technical man who can tell him about 
the “‘water ratio” and the ‘‘fineness modulus.” 
These are keys to the knowledge not only of how 
to make blocks but how to make money.

CONTINUAL TESTING NEEDED 


When the manufacturer gets on easy terms 
with these fundamentals, when he puts _ his 
materials together correctly (and by correctly we 
mean to make the most and best blocks for the 
least money) instead of throwing his profits out of 
the window simply by not knowing how; when 
the manufacturer gets started, he should know 
all the time how good his products are. The old 
monkey business of hitting a block with a hammer 
or throwing it on the ground is only guesswork. 

Concrete products manufacturers in a large 
American city recently made co-operative ar- 
rangements with a testing laboratory to pick up 
so many samples at regular intervals (about 
twice a month) and tell them just exactly how 
good their products are. 

In this way, by making blocks up to a recog- 
nized standard, the concrete building unit will 
come in time to mean something, not anything. 
The manufacturer should always do a little better 
than the building regulations require of him and 
adopt every legitimate means to force all manu- 
facturers to do the same thing. That sort of thing 
is possible only by organized effort. Nor should 
products manufacturers be content to organize 
merely among themselves; they should be active 
in the study of how to make better concrete cheaper 
along with consulting engineers, contractors, 
architects and technical men who know that to 
know how saves money. 


LEARN FRoM OTHERS 


Nobody can know today’s know how quickly 
unless he is taking every opportunity to find out 
what other men are learning. The bigger and more 
successful manufacturers of concrete products 
are members not only of the Concrete Products 
Association in which they join with others of their 
own kind, but of the American Concrete Institute 
where they are among the first to enjoy a knowl- 
edge of those developments which help them to be 
more successful. One products manufacturer who 
went from New England to attend the Institute 
convention held in Cincinnati in January, 1923, 
told me he saved precisely $1500 by what he 
learned from others at that meeting about the 
equipment needed to do a certain thing in his plant. 

There is no commercial equipment made, so far 
as the writer knows, which uses a mix of such a 
consistency as to produce concrete of maximum 
strength. The maximum strength is not necessary. 
It is a question if it is desirable. There are other 
things besides strength to be considered. Some 
equipment is better than others but no equipment 
is of any use without a knowledge of how to get 
the best out of it to meet the market demands. 

More demand for concrete building units is the 
result of economic pressure; continued demand will 
come from more and better organized knowledge 
of how to make the products.

Output 


Every maker of concrete products is obviously 
interested in knowing how many blocks or bricks 
his machine will turn out. 

The number of blocks he gets depends largely, 
in fact almost entirely, on two things: simplicity 
of design and reliability. 


Cleveland Builders’ Supply Co., Cleveland, Ohio 


And because they are simple, sturdy, uncom- 
plicated machines that are absolutely dependable, 
Anchor equipment will turn out more blocks or 
bricks in a year than you can get from any other 
machinery that you can put into your plant. 

Because they are simple in design, breakdowns 
are few and far between. And when repairs are 
needed only one machine and one or two men are 
affected, not your whole plant. 

That is another reason why these machines can 
go on, day after day and year after year, steadily 
piling up their production totals, with unbroken 
repetition, until they have outdistanced all other 
equipment. 

They are simple. They need few adjustments. 
They are strong. They are sure. That is the story 
in a nutshell. Users of Anchor equipment know 
this. They know that they can depend on Anchor 
machines to exceed all others in profitable output. 

Output depends on plant equipment and labor. 
For instance, if equipment is available to bring 


material right up to the machines, and take 
away the blocks, he will turn out more than if he 
were carrying them some distance to and from 
the machine. 

Often times estimates of production are based 
on ideal conditions. Such promises of production 
do not work out in the shop. 

For that reason, Anchor equipment is not sold 
on the basis of a definite number of units of out- 
put per day or per year. Instead Anchor machines 
are sold on the basis of reliability which means 
that when conditions are equal, Anchor will turn 
out more units per dollar invested, and more 
units per man than any other equipment. 

The Anchor Company points to letters signed 
by Anchor users. Anchor refers to the plants 
where its equipment is in use every day. Among 
these are numbered the most stable and profitable 
plants in the country. 

These plants show what Anchor has done in the 
past. They show how Anchor has performed. They 
tell the remarkable story of profitable production 
with Anchor equipment. 


Cleveland Builders’ Supply Co., Cleveland, Ohio 


One of the biggest building supply companies in the country, has confidence 

in its concrete block department. It is paying well. More and more building 

supply dealers are going into the concrete products business each month. 

Besides the two strippers and Hobbs machines shown in this picture, two 

more strippers are now being installed. Each of the block machines and 

tampers shown in these pictures has been in continuous operation for more 
than eight years. Practically no upkeep expense

Every day more concrete products plants join 
the procession of Anchor users. And one of the 
chief reasons is the Anchor System. 

Every day both large and small plants are 
finding that the Anchor System is the road to 
profits. 

Buy Small Units—Add (not discard) as you 
grow; that sums up the Anchor System. By means 
of the Anchor System a number of small inde- 
pendent units, simple practical machines each 
operated by one, or possibly two men, give you 
maximum production. 

The Anchor System is best because of its: 

1. Small Investment—Buy a single unit and add 
as you grow. Start with small capital. As your 
demand increases, install more units. All your 
money is thus always working. 

2. Flexible Outpul—When demand is light, run 
few units. When demand is heavy, run as many as 
needed. 

3. Continuous Production—Entire production 
never stopped on account of breakdown or adjust- 
ment. Only one unit affected, loss is small. 

4. Few Breakdowns—Simple construction of 
strong Anchor units makes breakdowns and _ re- 
adjustments extremely rare. 

5. Variety of Products—Makes rock, plain, 
panel and special blocks all at the same time, 
one kind on each machine. ‘This’ means, 


6. Timesaving—No need to be constantly 
changing parts. This saves wages; avoids trouble 
and delay; speeds up production; increases output. 

7. Satisfied Workmen—Never necessary to lay 
several men off because one of crew is absent. 
Never need to take a man off his regular job while 
others of crew make adjustments. 

These are the reasons why you find both big 
plants and smaller ones following the Anchor 
System. 

These are the reasons why every day the pro- 
cession of Anchor users grows in length. They are 
learning that tn the long run the Anchor System pays. 

Not long ago the Cemprod Engineering & Con- 
struction Company built, at Baltimore, Md., 
what was then the largest cement brick plant in 
the world. In this huge plant they installed the 
Anchor System entirely. 

Since then they have built a still larger plant at 
Philadelphia, now the largest in the world, and 
again they chose the Anchor System. 

This large firm has ample financial resources and 
made extensive investigation before they bought 
Anchor equipment. But like many others, they 
learned that the Anchor System of small inde- 
pendent units pays best in the end. If this is true in 
big plants, think what it means to the small plant! 

The Anchor System Insures More Blocks per 
Dollar Invested.

The Hobbs Machine 


THe Hobbs block machine has become known 
throughout the world as the great general purpose 
machine. There are more Hobbs machines in 
operation today than any other type. 

Added improvements in design of the Hobbs 
strengthen its claim to that already well-earned 
title. 

The Hobbs is a quality face-down wet-process 
machine with a range of 2000 sizes. It makes the 
finest faced blocks, and yet makes common blocks 
with great speed. 

The Hobbs is made in two sizes, the Senior and 
the Junior. All of the following information applies 
to both machines, except in the matter of block 
sizes. It must be remembered that the Hobbs 
Senior makes any size of block up to 12 by 12 by 24 


inches and the Hobbs Junior any size up to 9 by 12 
by 16 inches. 

The Hobbs is either a veneer, a hollow block, 
or a two-piece wall machine, whichever you desire 
to turn it into. 

To change it from a hollow block to a veneer 
block requires the longest of any change; this 
takes only five minutes. 

Changing from a 4-inch to a 6-inch veneer takes 
only five moves of the bare hands. 

Any regular length and any thickness in the 
wall from 3 to 12 inches is possible by these speedy 
and easy adjustments. 

But what has aroused such wide spread com- 
ment about the Hobbs is its remarkable range for 
any height of block in the wall. 


Concrete Products Machinery 11 


The Hobbs—Every Move Counts 


Every Move Counts—That’s the secret of the 
Hobbs speed. For instance you can make frac- 
tional blocks as quickly as whole ones, and on the 
same pallets. The automatic dividing plate is in 
serted and drawn with the cores; there are no 
hand inserted dividing plates. 

The Hobbs also makes whole blocks faster 
than most other machines, because, unlike other 
machines, when making hollow blocks the cores 
are inserted after you put in the facing and before 
you start tamping. 

No time is lost stopping the tamping to insert 
the cores. 

Because the Hobbs is built true, you can make 
changes quicker than on any other machine, 


The Hobbs makes blocks quickly—makes changes 
quickly. 


Almost an endless variety of sizes and faces is 
possible with the Hobbs. 


Its output— 2000 distinct sizes of any one style 


such as rock, plain or panel-faced blocks—is 
nothing short of marvelous. 


Think of it! Most block machines have a range 
of five to forty sizes, and the Hobbs has 2000. 
And remember every one of these 2000 sizes is 
made with the one back plate, one front standard 
and one frame that make up the regular Hobbs 
machine. 


With the Hobbs, you are sure that with small 
cost for plates, you can make any size you will 


ever need. 
You can make fractional sizes just as quickly as 
whole ones.

The Hobbs Is Built Right 


Tue Hobbs is designed properly and constructed 
with extreme care. It is built to last. 

Every part is machined on costly and accurate 
jigs. That means that every part is true. All 
parts are interchangeable. 

For this reason when you order a repair part, 
you are sure that it is going to fit. You know that 
you will not have any filing or fussing to make it 
fit. 

Every adjustment is absolutely positive. No 
part can slip without shearing a pin or bolt. 

It is impossible to set the machine in any way 
but the right way. It has no set screws. A pin or 
bolt must be put into an accurately drilled hole. 

Every block must be absolutely true in all its 
dimensions. No other kind can be made on a 
Hobbs. The mold box will stay rigid and true no 


matter how long or hard you use it, because it 
is constructed correctly. 

Long and costly experiments have brought the 
Hobbs to its present simple perfected form. It is 
stout and strong; it weighs at least twice as much 
as any other machine in the same price class. 

The frame is heavy and is graceful in design. 
The back plate is made exceptionally strong. 
The front standard and end doors are heavy 
enough to stand rough usage, but their weight 
is balanced by a special device so that virtually 
only the weight of the block is lifted. 

It is impossible to make a wetter block than 
the Hobbs makes, because the oval cores form 
arches that prevent the concrete from sagging. 

With the Hobbs cores you can make concrete 
just as wet as you could in making a solid block.

Description in Detail 


The Frame 


Tue frame of the Hobbs is constructed of the best gray iron 
properly braced to insure a rigid base for the machine, and 
is accurately finished to furnish a true surface on which 
the back plate is adapted to slide in adjusting. 


The Front Standard 


The front standard to which the face plates and end 
doors are attached is hinged to the frame. It is provided 
with arms or lugs on which the end doors are hung. These 
arms are in turn provided with holes which allow the end 
doors to be adjusted lengthwise of the mold box to vary the 
length of the mold box from 16* to 24 inches. 


To illustrate: When it is desired on the Hobbs Senior to 
have a mold box 16 inches long each door is moved in four 
inches or as far as possible. To make a 20-inch mold box 
either door is moved in four inches, and to make an 18-inch 
mold box the other door is also moved in two inches. A 17, 
19, 21, 22 or 23-inch mold box is made in like manner. The 
door jambs are also moved in to correspond. 


This feature is original and saves you money, for it 
gives you many machines in one. Compare this positive 
adjustment with that of other machines. 


The front standard is also provided with numbered holes 
by means of which the face plate is adjusted up or down 
to vary the depth of the mold box from 3 to 12 inches. 


The face plate bar has steel pins that fit easily in these 
holes. To raise or lower the plate for different thickness 
of block and to drop in end plates to correspond takes but 
a moment. 

This feature provides you with a machine that will make 
any style of block, either 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 
inches in thickness or depth in the wall. 


The Back Plate 


The back plate—the vital part of the machine—is a mar- 
vel of ingenuity. It has a long bearing surface in contact 
with the frame that is accurately machined which holds 
it square and rigid. 


The face plate and end plates are clamped to the back 
plate, and insure an absolutely square block. The back 
plate is adjustable toward, or away from, the front stand- 
ard to vary the width of the mold box. That is, after 
removing a steel pin from each side, it slides easily and 
quickly,ton,the finished frame to any desired position to 
accommodate a face plate for a block either 3, 4, 5, 6, 7, 
8, 9, 10, 11 or 12 inches high when set in the wall. 


The value of this adjustment is not fully appreciated 
until you operate the machine. You cannot make even 
one-half of these heights with any other machine. Anyone 
who can read can make this change, for each hole in the 
frame is numbered. To set up for say a 10-inch block, the 
back plate is moved so that the hole at the side registers 
over the hole in the frame marked 10 and the pin inserted. 


The entire front surface and the top edge of the back 
plate are accurately machined. Ears with holes are placed 
on the top edge of the back plate. These furnish means 
for attaching any device that may ever be needed, such as 
a feed table, return corner, silo or circle attachments. 


Skeleton End Doors 


The skeleton end doors are not only adjustable length- 
wise of the mold box, but are provided with arms by means 
of which they are adjusted one inch in or out to accommo- 
date a like adjustment of the back plate. 

For instance, the 4-inch doors can be used with a 4 and a 
3-inch width of mold box; the 8-inch doors can be used 
with an 8 and a 7-inch width of mold box, and the 12-inch 
doors can be used with a 12 and 11-inch width of mold 
box; 6 and 10-inch doors are also used in this manner. 

The doors are provided with means for carrying the 
different depths of end plates for the different depths of 
the mold box. 

These doors have a latch which locks and squares all 
parts with the back plate. Bearing down on the handle 
of the latch locks the door, and raising releases it.

Au of Hobbs plain face plates (not end plates),

reversed are a regular panel face plate for 
making a panel faced block. This clever expedient 
reduces the number of parts, the weight and the 
price. Remember you get two plates for the price 
of one. 

Hobbs face plates approach perfection. They 


are highly finished, absolutely accurate in all 
dimensions. 

A wide variety of special and fancy face plates 
can be furnished to order. We make no attempt to 
show here the many types of cobblestone, brush- 
hammered, tooled, and other designs available. 

Unless otherwise specified all machines will be 
equipped and repair orders filled with rock design

Concrete Products Machinery 15 


The End Plates 


UNLIKE other machines, the end plates in the 
Hobbs are provided with means by which they 
are inserted dovetail fashion into ways in the 
skeleton doors. No pins or set screws are used. To 
change the end plate you merely lift out of the 
skeleton door and insert another of the style and 
size desired. This takes but a few seconds. 

This construction simplifies the machine and 
lessens the number of parts. Any even width of 
end plate in any depth from 3 to 12 inches will fit 
the same width of either right or left skeleton door. 
Owing to their peculiar design odd widths of end 
plates must be made in rights and lefts. See 
“Skeleton Doors.” 

All end plates make blocks that run full width, 
such as 8, 10 or 12 inches. 

When it is so specified, special end plates can be 
furnished that, in making return corners, will 
make the block a quarter of an inch less than the 
regular thickness or width of the block. 

To accomplish this the top of the end plate, 
when the machine is closed and ready to make a 
block, is a quarter of an inch below the top of the 
back plate. After the top of the mold box is struck 
off as usual the striker is held 
with the edge bearing on top of 
the return end plate and the 
surplus concrete removed with 
one stroke. This is necessary, of 
course, only with return corners. 
When making regular blocks all 
parts are flush or even with the 
top of the mold box. 

When using a rock return end 
plate at each end of the mold box 
for pier work a block is made just 
a quarter of an inch less in thick- 
ness than the regular block. For 
instance: An 8 by 8 by 16-inch 
block made in this manner for a 
pier would be exactly 734 by 734 
by 1534 inches. 

At a small extra cost, attach- 
ments can be furnished for raising 


the face plate in the mold box one-quarter inch 
and thus all blocks will be one-quarter inch under 
the usual thickness. Then all end plates are flush 
with the top of the 
back plate at all 
times and every 
block will come 
right for pier work 
or corners. For in- 
stance, blocks which 
it is customary to 
make in even 4, 6, 
8, 10 or 12 inches in 
thickness in the wall 
would be respect- ine 
ively 334, 534, 734, 1a 3 :

Cores 


THE cores are carried by the back plate and move with 
it when adjusting for various widths of the mold box. 
These cores are oval in shape to produce an arched opening 
which prevents a breaking down or sagging of a wet mix- 
ture, thus producing a stronger block than with air cham- 
bers of other shapes. From an engineering and _ practical 
standpoint this is the proper and only way to core out 
material in a concrete block. 


A 12", 10" and 8” Core 


With these small oval cores a mixture as wet as will 
stand up can be used. It is impossible to use a wetter 
concrete on any machine from which the block is removed 
as soon as made. 


The cores are not rigid when in the mold box but have a 
slight play up and down. This characteristic permits the 
inserting of the cores after the facing is placed in the mold 
box and before the concrete is put in. 


The cores being small and oval the first tamping forces 
the material under the cores and raises them a trifle— 
then the last tamping on top of the cores tamps them down 
solid and produces a very dense block all around the core 
openings. 


This means that the tamping is not stopped to throw in 
the cores as with other machines and the result is that 
more blocks may be made in a day. This is an especially 
valuable feature when using a mechanical tamper. Every 
Move Counts. 


With these small cores you are able to core out the 
regular air space no matter what length of block, even if 
only four inches long. The cores are far enough apart to 
permit the use of gravel or stone the size of a small egg. 


The cores are inserted into and removed from the mold 
box through openings in the back plate, by means of a 
hand and foot lever. There is a bar connecting the core 
rods to which the hand and foot levers are attached and 
by an arrangement on this bar the cores are starting one 
at a time. This is of great value in removing the cores 
from a wet mixture because it enables you to start them 
easily. 


To accommodate the different sizes of cores that may be 
used with this machine, adjusting plates are provided that 
are carried by the back plate. These adjust the openings 
in the back plate for the different sizes of cores which vary 
in depth but not in width. 


The standard Hobbs back plate accommodates cores 
which give 33 per cent air space in 8-inch wide blocks; 
37 per cent air space in 10-inch blocks, and 38 per cent in 
12-inch blocks. An oversize back plate can be furnished 
which accommodates 40 per cent cores in each width. 


When making a solid or veneer block the cores are 
withdrawn and the core openings in the back plate are 
closed with plates provided for the purpose. Slotted cores 
are provided to be used with dividing plates when making 
fractional cored blocks. 


Dividing Plates 


THE dividing plates are made of steel and are a quarter 
of an inch thick which provides for the mortar joint in 
making fractional blocks. They are attached to the core 
shaft with a slotted core when dividing hollow blocks and 
are inserted and removed with the cores, positively without 
attention or lost time on the part of the operator. 


Whenever the dividing plate is used sectional face plates 
are used. This construction allows the face plate to be 
adjusted up or down using the same dividing plate. The 
back plate is provided with slots in which the dividing 
plate is adapted to ride when moving in or out of the mold 
box. This allows the back plate to be adjusted in and out 
while the dividing plate is in position. This construction 
permits the use of one size dividing plate for dividing all 
sizes of blocks. 


For instance, in dividing a 4-inch square block the 
upper front corner of the dividing plate is in the mold box 
and when dividing a 12-inch square block nearly the entire 
plate is in the mold box. 


When using the dividing plate for solid or veneer blocks 
the core is removed and the dividing plate only is left on 
the core shaft. It is then inserted through the mold box 
until it comes against the pallet and is left stationary. 
The blocks are lifted away from the dividing plate and 
thus fractional solid blocks are made without one extra 
move.

Sectional Face Plates 


One of the original and most valuable features of the 
Hobbs is the use of sectional face plates for making frac- 
tional blocks. 

In making all blocks, the face plate or plates are attached 
by means of steel pins to a steel bar that is accurately 
drilled with a series of holes to receive these pins. These 
holes are so laid out that no matter in what position two 
or more face plates are attached to the bar they are one- 
quarter inch apart and the slot so formed when the machine 
is closed lines up exactly with a quarter-inch slot in the 
back plate. 

These slots in the back plate occur every four inches and 
are in the center of the core openings. Therefore, if you 
attach a steel dividing plate that is one-quarter inch thick 
to a core shaft with a slotted core, in making hollow blocks, 
this combination core and dividing plate can be inserted 
and removed with the rest of the cores without attention 
or loss of time by the operator. 

- The dividing plate rides in the slot in the back plate 
and is guided and held by the slot between the fractional 
plates, no matter whether the sectional plates are in the 
bottom of the mold box for making blocks 12 inches thick, 
or whether they are near the top for making 4-inch veneer. 

Therefore only one size of dividing plate is needed for 
operating the Hobbs to make any of the 2000 sizes that it 
is adapted for. And, more interesting still, is the fact that 
the dividing plate, no matter in what position, is always 
even or flush with the top of the back plate. This gives a 
free strike off and makes the Hobbs the fastest machine on 
the market for making fractional and special sizes. 

This is why real Broken Ashlar can be made as cheaply 
as common work. A study of the Hobbs will convince you 
that this is reasonable. 


If the Hobbs were no better than other machines in all 
other respects this feature alone would make it the best. 
By this construction the Hobbs also saves you money 
when you require extra plates. For instance, if you re- 
quired an 8-inch width of face plate 6 inches long, in addi- 
tion to the Hobbs regular equipment you would need to 


Concrete Products Machinery 7 


buy only an 8 by 6-inch plate at a small part of the cost of an 
8 by 24-inch fractional plate dividing by a groove into a 6 
and 18-inch section. With the Hobbs this 6-inch plate can 
be attached to the bar with a 16 or a 12 and a 4-inch length 
which are all regular plates. 

Five dividing plates are needed if you want to make 
bricks or a large number of very small size blocks, but other- 
wise only one or two dividing plates are required for every 
size. Other machines possessing only one-tenth of the range 
of the sizes the Hobbs has, require ten times the number 
of dividing plates. 


The following sizes of face plates are standard. 
Face plates of any size will be made to specifica- 
tion.

Wherever face plates or end plates are mentioned 
in this handbook the first figures mentioned 
determine the height of the block 
in the wall. For instance, a 12 by 4- 
inch face plate is for a block that 
sets 12 inches high in the wall arid is 
four inches long. A 4 by 8-inch 
end plate is for making an 8-inch 
return on a block 4 inches high in 
the wall. 


Pallets 


Tron or wood pallets up to 17% inches 
thick can be used on the Hobbs. By 
special arrangement this machine can be 
equipped to use any standard make of 
iron pallet.

This range of styles and sizes enables you to 
avoid monotony in your work. Apart from Real 
Broken Ashlar, which may be made with this 
equipment, no two jobs need look alike. You can 
run alternate courses of different heights or styles 
of blocks. You can use 12-inch high blocks in 
heavy foundations and large structures and gain 
a tone and character impossible with small blocks. 
This means that you can approach and even sur- 
pass the best stone work for constructing large 
buildings.

Special Hobbs Attachments 


Hobbs, Jr. equipped with Bay Window attachment 


Tue Hobbs machine has been so designed that 
attachments for special sizes and shapes can be 
put on easily and operated quickly. 

The most important of these is the Octagon or 
Bay Window Block attachment. This attach- 
ment positively never fails to work. To use it 
remove either the right or left end plate and attach 
the bay window device instead. 

A separate attachment only is required for 
different width of mold box for different heights of 
blocks. It can be raised or lowered to make octagon 
blocks in any thickness from 4 to 12 inches. It can 
be set at any angle from 20 to 75 degrees. It is 
used in combination with any regular face plate 
under 20 inches in length. Only a face plate for the 
4-inch return is required. 

Almost the regular amount of air space can be 
had. Regular pallets are used and the dividing 
plate can be used for making all lengths of bay 
window blocks from 4 to 20 inches. Jt ts absolutely 
positive in all its adjustments. 


The Hobbs Return Corner Attachment for making 
a longer or shorter return than the thickness of the 


block consists of a device for bolting on top of the 
back plate which in combination with a special end 
plate forms the return. It operates easily and 
quickly and can be furnished in all sizes. 

Circle or Silo Face and End Plates are furnished 
to order for any radius. 

The Anchor engineering department and the 
Anchor pattern and machine shop are prepared to 
make all kinds of special plates and attachments 


to your order.

The Hobbs Makes Almost Every Size and Face 
Real Broken Ashlar 


Real Broken Ashlar wall, see diagram on opposite page 


THE marvelous range of sizes and faces possible 
on the Hobbs makes it especially suited to making 
real Broken or Random Ashlar. 

It is generally laid up in rock-faced blocks, but 
it can be used in tooled, plain or hammered face. 
The Hobbs was designed and equipped particu- 
larly for this work. 

You cannot imagine how much broken ashlar in 
concrete blocks made with Hobbs plates looks 
like real stone. You simply have to see it. 

By using 18 different sizes (or less) of blocks and 
by reversing some of these, you will not notice two 
blocks in the wall that look alike, unless you search 
for them. 

This eliminates the monotonous appearance of 
rock-faced block as made on other machines. 

Imitation ashlar block with false joints are too 
artificial to have a pleasing appearance. 

Hobbs regular equipment is adapted for making 
real broken ashlar for a 4-inch unit system. Blocks 


that lay 4, 8, and 12 inches high in the wall and 
each height in blocks 4, 8, 12, 16, 20 and 24 inches 
in length are used. With Hobbs regular equipment 
each one of these 18 sizes can be made in 4-inch 
thick veneer or in 18-inch blocks with about one- 
third air space. Each block can also be made 
with a 4 or an 8-inch rock or plain faced return 
corner. 

Plates for making blocks 3, 6, 9 and 12 inches 
high for a 3-inch unit system of broken ashlar can 
also be furnished. 

In California this broken ashlar work is usually 
made in 4-inch veneer and backed up with cheap 
bricks or blocks. One or two of the smaller sized 
blocks can be made 8 inches in depth or thickness 
and used as a header to bind the outer to the 
inner wall. Or it can be laid in a two-piece wall and 
tied with metal ties or made in solid or cored 
blocks for any thickness of wall. End plates for 
making other thicknesses are inexpensive.

The Hobbs Makes Quality Blocks 


AS FRACTIONAL blocks are made on the Hobbs at 
positively no increase in time or trouble by means 
of the automatic dividing plates, it costs no more 
to produce real broken ashlar than it does the 
same number of cubic feet of 8-inch high standard 
size blocks on the Hobbs or other machines. 

The time that is lost in making the 4-inch high 
blocks is gained in making the 12-inch and the 
average time is the same as for making blocks 
8 inches high. The only extra cost is for setting 
the work. 

Stone masons that are familiar with laying 
broken ashlar in stone work as a rule need no 
instructions. Others learn easily and like the work, 
for it is very interesting. If you will devote an 
hour or two to each job and detail the work so that 
the number required and the position of each size 
stone is determined, then any one who can set 
any kind of block can lay broken ashlar. By get- 
ting out rough detailed plans you know exactly 
how many of each size block is required for the 
job. This list of sizes can then be given to your 
yard man and the exact number of blocks deliv- 


ered on the job. The mason then sets the blocks 
according to the rough drawing. By this method 
you can figure to a cent what a job will cost; there 
is no guesswork. 

Real broken ashlar requires at least three differ- 
ent heights and various lengths of block that will 
bond together properly. 

Anchor regular equipment makes blocks in 
lengths up to 24 inches and in three heights—4, 8 
and 12 inches. Extra plates can be furnished for 
making ashlar in blocks 3, 6 and 9 inches high, and 
also 3, 6, 9 and 12 inches high and in any face 
desired. The 4, 8 and 12 ashlar is the best for block 
work. You simply lay it “two against one,” that 
is, you set two 4-inch high blocks against an eight 
and a four and an eight against a twelve. The 
vertical joints will thus never be more than two 
blocks high. The horizontal or bed joint should 
never be longer than the length of four or five 
blocks. Two or three blocks should never be laid 
against two nor one against one except at openings 
or at the start or finish of a wall. This is simple, and 
is quickly learned by anyone. 


This diagram shows method of detailing broken ashlar, 

It is optional whether this work is detailed as shown or 

whether it is left for the mason to set as he chooses. 
Scale: 1-16. Each square equals sixteen square inches.

Striking and Finishing Device 


for the Hobbs Jr. Block Machine 


The tamper is then thrown into operation. The 
first tamp foot down brings the finishing plate in a 
position shown in Figure 2 and it is only necessary 
to run the tamper an instant to finish the back of 
the block. This finisher plate is so arranged as 
to positively prevent any material from  stick- 
ing to it. 

As soon as the tamper is thrown out of operation 
the finisher is automatically thrown back into the 
position shown in Figure 1. This position gives 
plenty of room for opening the mold box and 
closing it again and for the insertion of facing 
material when such is used. 


Fig. 1 


In answer to a widespread demand for some 
device which would mechanically strike off and 
finish the back of the Hobbs block, Anchor has 
developed this exceedingly simple and effective at- 
tachment which will go on any Hobbs Jr. machine 
without drilling any holes whatever into the 
machine. This attachment can be placed on the 
machine with the use of a wrench and screwdriver 
by anyone in an hour or less. 

Figure 3 is a phantom view of the Hobbs ma- 
chine showing how the Striking and Finishing 
Device is mounted. In Figure 3 the hopper is 
thrown forward in a position ready to receive the 
concrete. 

After the block has been tamped the lever 
(No. 4) is moved upward thus striking off the top 
of the block evenly and at any desired height 
above the top of the mold box. 

The amount of surplus material left to be driven 
into the back of the block is controlled by a 
simple adjustment on the Striker Plate. After the 
block has been struck the Striking and Finishing 
Device is in the position shown in Figure 1. Fig. 2 


Concrete Products Machinery 3] 


This inexpensive device increases production a 
great deal. In addition to this it insures uniform 
blocks because every block is struck off at exactly 
the same height. The rigid finisher plate gives a 
true and smooth back to the blocks. 

Use of this device is strongly recommended to 
all Hobbs Block Machine operators. It will pay 
for itself in an extremely short time by increasing 
production. In addition to this the quality and 
uniformity of the blocks will be much improved. 

When the Striking and Finishing Device is pur- 
chased with the block machine it is shipped 
mounted on the machine. If you already have a 
Hobbs Junior and would like to mount one of 
these devices, proceed as follows: 


Fig. 3 


Remove the cold rolled strip No. 4 as 
shown in the repair parts guide on the Hobbs 
machine. If your machine has no cold rolled 
strip No. 4 on the back plate, it is only nec- 
essary to run a 5¢-inch U.S. Standard tap through 
the holes in the top of the back plate. Then saw off 
the rib which is cast on the back plate. Place the 
Striking and Finishing Device on the machine in 
the general position shown and fasten the feed table 
of the device to the back plate with the screws 
which formerly held the cold rolled strip No. 
4. Then tighten the clamp, which is a part of 


the straddle casting No. 8, securely to the core 
rod support casting of the Hobbs machine. 

Next remove the lever which operates the cores 
of the block machine, slip on the catch release 
collar No. 5, and replace the core draft lever. 

To adjust the catch release collar, place the Strik- 
ing and Finishing Device in the position shown 
in Figure 1. Then tighten the catch release collar 
in such a position that when the front end of the 
cores is about 14 inch from the pallet, the curved 
rod in the catch release collar engages the catch 
release so that it in turn raises the catch No. 9 
sufficiently to permit the feeding hopper to go 
forward. 

You will find that with the machine at hand the 
instructions are easily followed, and that when 
the device has once been installed, it is practically 
fool-proof and will give very little trouble.

The Anchor Stripper 


PLAIN-FACED blocks are constantly in demand, 
and their popularity is growing daily. The best 
and fastest way to make them is on the Anchor 
Stripper. 


This process permits the use of an extremely wel 
mixture. All the concrete receives a direct blow 
from the tamper because the tamp feet completely 
cover the block. 


Finally, to add to these advantages, the block is 
stripped out of the mold box. This stripping action 
is not only the fastest known means of delivering a 
block, but it is also the best. Every face is trowel- 
ed perfectly. 

Users of the Anchor Stripper find in it the same 
high grade material and accurate workmanship 
that have made the Hobbs Block Machine and the 
Anchor Tamper so favorably known. 


All parts of the Stripper are accurately ma- 
chined on jigs. The mold box is bolted rigidly 
together, thus insuring for you an absolutely true 
block at all times. 


The Anchor Stripper is extremely heavily and 
carefully built. And like other Anchor equipment, 
it is simple, sturdy and low-priced to conform to 
the Anchor System of big production at low cost. 


You will find some of the biggest plants in the 
country using the Anchor Stripper. 


It is made by “Anchor”: It is guaranteed by 
the name: It will do what Anchor says ut will. 


The drawing on opposite page shows the stand- 
ard type of core furnished with the Anchor Stripper. 
The machine is made in two standard sizes: 16 and 24 
inches. Each different length machine will make 
blocks any width of wall, such as the 8, 10 or 12 
inches, by getting the necessary cores and pallets 
to conform with the size wall desired. All blocks 
734 inches high. 

The standard size cores furnished with the ma- 
chine give 40 per cent air space. In localities where 
building restrictions will not allow as great an air 
space as furnished with the machine, there can be 
furnished, when specified, a lesser percentage air 
space, such as 33 per cent, or any percentage of air 
space desired. Anchor can also furnish any other 
shape of core to match pallets you already have. 


Iron pallets are used on this machine. These 
may be purchased from Anchor or made in your 
local foundry with necessary patterns. 


First of all the Anchor Stripper makes a quality 
block. The Erie Cement Products Company, 
Sandusky, Ohio, writes as follows: ““My Anchor 
Stripper is working fine and turning out the best 
plain block made in Erie County. Am having big 
sale for them and am well pleased with the 
machine.” 


These blocks can be laid either face out. They 
are made wet—tamped hard.

Anchor does not believe in exaggerated produc- 
tion claims or claims based on test run under perfect 
conditions and as much of this depends on the 
operators and facilities in handling, it is impossible 
to say offhand what could be done in your plant. 

Anchor can refer you to many plants using 
the Anchor Stripper that are averaging 1200 to 
1400 blocks per day. In fairness we must state 
that this is above the average but shows what 
can be done under good conditions. 

Seventy-five per cent of blocks used in most 
localities are plain face. This is a practical machine 
for producing plain-faced blocks. A careful study 
of actual production figures shows that users of the 
Anchor Stripper get more blocks per dollar than any 
other equipment can give and the original in- 
vestment is much less. 

Make your plain blocks on Anchor Strippers; 
your faced blocks on Hobbs face-down machines. 
Buy a single unit and add as you grow. 

That’s the Anchor System—low initial cost, 
profitable operation. 

Every day more plants—both large and small— 
are learning that in the long run, the Anchor 
System pays.

Known as the cleanest and neatest products plant in U.S., is one of the 

oldest plants and one thal is making real money—has enjoyed more editorial 

publicity in trade journals than any other plant. Mr. Barriball has ex- 

perimented with many makes of machinery but has now settled down to 

Anchor equipment exclusively, makes quality products, is an Anchor 
booster and a money-maker. 


Striking evidence of the rising popularity of 
plain-faced blocks may be seen in the Hoover 
Model “Home, Sweet Home” built recently on 
the Executive Grounds at Washington as the 
nucleus of the Better Homes in America Move- 
ment sponsored by the General Federation of 
Women’s Clubs of the United States. 


An Anchor Stripper was chosen to make the 
blocks used through the entire house. The Home 
is acharming modern reproduction of the old home- 
stead on Long Island where John Howard Payne 
wrote his immortal song, ““Home, Sweet Home.”

The Anchor Continuous Air-Space Block Machine 


AMPER 
HE CO, 


RAPS ORR ff 


Tue Anchor Continuous Air-Space Block Ma- 
chine was designed to meet the insistent demand 
for a concrete block which was absolutely frost 
and moisture-proof. 


It is a recognized principle that double wall 
construction is essential to a good building. And 
it is evident that the best way to tie these two 
walls together is with heavy steel ties made right 
into the wall itself—nol laid in the mortar joints. 


The Anchor Continuous Air-Space Block is 
the solution. Each block is tied together by four 
ties or anchors, which are made right into the 
block. These anchors are made from heavily 
galvanized one-quarter inch steel wire. They are 
five inches long with a one-inch right angle bend 
at each end. 


You can purchase these anchors at any time 
from the Anchor service department which makes 
and furnishes them at cost. The price is usually 
about half a cent each. 


The Anchor Continuous Air-Space Block can 
be laid in the wall more rapidly than any other 
block because there are only two surfaces upon 
which to spread mortar and these are wide and 
straight. 

Moreover, these blocks are handled with hooks 
inserted beneath the anchors, which greatly 
increases the ease and speed of laying. The air 
space is 3314 per cent. 


The Anchor Continuous Air-Space Block Ma- 
chine is made in two sizes—the Standard and the 


Junior. 


The Standard size makes blocks that lie in the 
wall 8 inches high, 24 inches long, and 8, 9, 10, 
11 or 12 inches wide, with corners and fractionals 
to match. 


The Junior Air-Space Machine makes blocks 
that lie in the wall 8 inches high, 16 inches long, 
and 8, 9, 10, 11 or 12 inches wide, with fractionals 
and corners to match. 


36 Anchor Concrete Machinery Co. 


The Anchor Continuous Air-Space Block is With Continuous Air- 
one which appeals to home builders and_ to Space Blocks you actually 
practical masons. These two things assure you build a double wall at the 
of a demand for your product. cost of laying a single wall. 


It is safe—and common 
practice—to plaster directly 
on the inner wall of these 
blocks. 


The Anchor Continuous <Air-Space_ Block, 
because of its peculiar design, can be made very 
wet. This results in a stronger block. Another 
thing—all of the bearing area of each block is 
bearing area in the finished wall. These are no 
cement webs which become worthless as bearing 
area when placed in the wall. 


The Standard Anchor Continuous Air-Space Block Machine

fractionals to match, consists of the following parts:

Anchor Continuous Air-Space 
Silo Machine 


Makes blocks that lie in a perfect 16-foot circle 
but can be laid in any diameter from 12 feet to 
20 feet. Note the groove to receive reinforcing. 

These blocks are used where an extraordinarily 
fine silo is required. The air space reduces freezing 
to a minimum. Practically no ensilage is lost 
through freezing in a silo of this type. While a 
silo made from these blocks costs more than one 
made from Anchor silo slabs, it costs no more 
than one made from ordinary silo blocks and is far 
superior.

Anchor Silo Slab Machine 


Makes two 4-inch silo blocks in each operation. 
Can be laid to the same diameters as the air space 
blocks. 

Since two of these slabs are made at each opera- 
tion they can be made very cheaply. A silo built 
from these slabs is fully as strong as one built 
from ordinary blocks and costs much less.

chines the Anchor com- 
pany can furnish this 
equipment to make 
silo blocks at a very 
reasonable price. 
Either of these silo 
machines will operate 
under any Anchor

changing the tamp 
feet. 

The same pallets as 
for making building blocks are used. 


Tue silo shown above is located on Lakewood 
Farm, six miles southwest of Rock Rapids, Ia. It 
is 50 feet high, 16 feet in diameter and holds 250 
tons. This silo is constructed from the Anchor 
4-inch silo slabs and is equipped with Anchor 
All-Steel Silo Doors. It has been full twelve times 
and there is not a leak or a cracked block in it. 
This type is the most economical silo made. 


Tue Anchor Steel Silo Door built entirely from 
steel with a fiber packed door. Each door con- 
stitutes complete frame, door, and ladder for 4 
feet of silo height.

Tue blocks in the above corncrib were made with 
attachments on the Standard Anchor Block Ma- 
chine. Two of these blocks are made in one 
operation. Each block contains three full holes 
and two half holes, giving 25 per cent open area. 
A ventilating shaft in the center provides perfect 
ventilation. This crib is 18 feet in diameter, 24 
feet in height, and holds 2,500 bushels of corn.

Anchor Concrete Brick Machines 
Made in Two Types—Face-Up and Face-Down 


THE day of concrete brick has arrived. Because - 
it can be produced at high speed and at low cost, = 
because of its excellence as a building material, 
and because it can be laid more cheaply, it is 
fast replacing the old-style clay brick. 

When properly made, concrete brick runs higher 
in compression and lower in absorption than clay 
brick. Another advantage is the uniformity of 
concrete brick—every one can be made exactly 
alike on Anchor Brick Machines. No kiln baking 
is necessary—no shrinkage or warping takes place. 

Because Anchor Brick are uniform in size 
and have sharp, clean corners, masons will lay 
approximately 20 per cent more Anchor bricks 
than others in a day. 

Uniformity of Anchor Concrete Brick also 
-means double the manufacturing output of 
usable brick— production at far lower cost than 
clay brick. 

It will pay you to investigate the manufacture 
of concrete brick. It’s a big-money business, 
easy to start; a fast-growing, permanent indus- 
try. Your production is sure to be profitable when 
you use Anchor machines. 

When the plant of the Adamantex Brick Com- 
pany, of Baltimore, Md., was built and put into 
operation by the Cemprod Engineering and Con- 
struction Company, New York, Anchor machines 
were installed. During more than a year’s opera- 
tion its daily output was more than 100,000 bricks. 

So efficient, so sturdy, so trouble-proof has this 
Anchor equipment been under continuous heavy 
duty that the Cemprod Engineering Company ray 
has since equipped another and still larger plant ANCH OR » 
at Philadelphia—the largest concrete brick plant FACE DOWN 
in the world—with Anchor brick machinery 
excluswely. The success and rapid expansion of 
this and other Anchor brick plants prove that 
there is big money in the manufacture of Anchor 
Concrete Brick. 

A quick, inexpensive way to get into the Con- 

crete Brick business is to follow the Anchor 

System—Buy a Single Unit andaddas you grow.

Anchor Concrete Brick Machines—Continued 


Ancuor Concrete Brick Machines are made in 
two distinct types—Face-Up and Face-Down. 
Both types have proved their efficiency and 
dependability under hard, continuous service. 


The Anchor Face-Down Machine is the fastest 
machine in the world for making common brick. 
Both machines will use either wood or pressed 
steel pallets. Either machine will be supplied 
with hand or power tamper. The hand-tamped 
machine can quickly be converted into a pow- 
er machine simply by changing the tamper. The 
machines with the power tampers are the same 
as those with the hand tampers attached, except 
for the tamping device itself. 


Standard machines make ten bricks—2 14 by 334 
by 8 inches in size, at each operation. Machines 
for making other sizes of brick will be built to 
your specifications. 


Exclusive Features of Anchor Power 
Brick Machines 


(1) Anchor Brick machines are small single units 
—no large investment required to start making 
concrete brick. As your business increases, add 
more machines. With any number of workers, 
your production of concrete brick is profitable 
under the safe and sound Anchor System of 
small units. 


(2) Anchor Brick Machines can be used under 
the famous Anchor Tamper—faster production. 


(3) Both machines are equipped with rigid feed 
table and heavy sliding hopper with adjustable 
cut-off plate. 

(4) All dividing plates are cyanide hardened to 
prevent wear. 

(5) Heavy housed bases—able to stand knocks 
and blows. 

(6) All parts are machined in accurate jigs to 
assure perfect brick. Repair parts, should they 
be necessary, will fit without alterations.

Anchor Face-Down Machine 


Tue Anchor Face-Down Machine—as the name 
indicates—makes the brick with the face down. 

The mold box has a polished steel face upon 
which the facing material is scattered. The coarse 
aggregate is pounded into the facing, insuring a 
perfect bond and a dense face. 

A rough or mottled face brick can be made on 
this machine by treating the face after brick are 
taken from the machine. 

After the brick are tamped, the hopper is pushed 
back, striking off the surplus concrete, which is 
carried back to the feed table. There is no waste. 
The pallet is then slipped into place, the bricks are 


given a half turn and carried away to their rack. 
The mold box is closed in an instant by merely 
throwing bed plate back into position. 

One reason for the surprising speed of this 
machine is the simple and efficient device for 
holding the pallet while the brick are being turned 
over. There are no triggers, catches or springs. No 
other machine has so practical and fast a means of 
delivering the brick from the mold box. 

The Anchor Face-Down Machine is the most 
popular brick machine in the country. It is the 
fastest machine for making common brick and yet 
beautiful brick can be easily made on it. 


Anchor Face-Up Machine 


Tue Anchor Face-Up Machine is used when it is 
desired to apply a face by floating, troweling or 
brushing it on. This machine makes the brick in 
the same position in which they are carried away. 

Like the Face-Down Machine this machine has 
a hopper which strikes off the surplus material 
after the brick are tamped, carrying it back on the 
feed table. To open the mold box, simply apply a 
slight pressure on the foot lever, and at the same 
time push the hand lever through a short range. 
This movement carries all the dividing plates 
straight back and swings the front plate down, 
leaving the brick in a position from which they are 
easily picked up and carried away. 

For straight-run face brick—only one edge 
faced—the facing is applied before the lever is 
thrown. When making header brick—one edge and 
one end faced—remove one bolt just inside the 
front housing and apply a short lever. This en- 
ables the operator to swing the front plate down 
and apply facing on the ends before the dividing 
plates are drawn. 

Past performance of this machine proves that 
it is unquestionably the best built and the most 
practical face-up brick machine. It is primarily a 
faced-brick machine, but will make common 
brick rapidly enough for profitable production.

The Famous Anchor Automatic Power Tamper 


*Tamps and Tamps Right”’ 


For years the Anchor Tamper has been standard 
equipment over every type and make of block, 
brick, tile and stave machine. There are more 
Anchor Tampers in operation than all other makes 
combined. 

In all sections of the country you will find it in 
operation over every brand of block machine. 
The reason is simple. The Anchor Tamper so in- 
creases the output of any machine—block, brick, 
that it soon pays for itself. 


tile or stave 

Added profits soon return the cost of the Anchor 
Tamper to its owner. In addition to increased 
profits, the Anchor Tamper makes a_ denser, 
stronger and more uniform product. 

The Anchor Automatic Tamper requires no 
floor space because it is mounted directly over the 
mold box. No extra workman is required to 
operate it. It has only one lever. The man who 
operates the mold box can throw it in and out of 
operation in a second. The Anchor Tamper does 
its work while the workmen are filling the mold 
box, thus requiring no additional time for the 
tamping operation, and saving a large amount of 
time. 

With the Anchor Automatic Tamper blocks 
‘an be made from a much wetter mixture, and 
are uniformly and firmly packed; thereby pro- 
ducing a block that is much stronger, cheaper 
and more waterproof than is possible by any 
other system. 

The Anchor Tamper is the one power tamper 
that is simple enough in construction to be 
practical. It is rapid in operation and requires 
only one horse power. And it is so simple in design 
that it is seldom in need of repairs. 

The fact that there are more Anchor Tampers 
in operation than all other makes combined is 
eloquent evidence that the Anchor Tamper, like 
other Anchor equipment, is dependable, that it is 
built to do its work right, and that it makes 
money for its owner.

How the Anchor Tamper Is Built 


THE improved tamper frame is now hot-riveted. 
The tamp rods have been increased in size from 
one-inch to 11!4-inch diameter which entirely 
eliminates all possibility of breakage. 

The Anchor Tamper has an improved crank- 
shaft construction. The tamping shafts are raised 
by heavy annealed steel crank arms, fastened in 
place on the driving shaft with a half-inch steel 
key and also securely clamped by means of a split 
hub. 

Improved tamp rod bushings now provide for 
take-up. 

The new and extremely simple Anchor brake 
device is so cleverly constructed that it throws 
each tamping rod in and out of operation in exact 
time and, in addition to this, when the tamper is 
thrown out of operation an eccentric automatically 
lifts all tamp rods clear of the crank arms so that 
virtually no power is used when block is being 
taken from mold box. 

Much of the success of the Anchor Tamper is 
due to the use of the special patented Shock- 
Absorber Pulley—another exclusive Anchor fea- 
ture. 

This drive pulley, 26 inches in diameter, is 
equipped with four heavy springs, thereby trans- 
mitting the power evenly through the crankshaft 
to the crank arms and preventing crystallization 
of steel parts. In addition to the easement pro- 
duced by the shock absorber, the part of the crank 
arms coming in contact with lifting guides is 
equipped with fiber rollers, further aiding in pre- 
vention of crystallization of steel parts. 

The fact that all working parts are fiber against 
steel—not steel against steel—means that noise 
is reduced to a minimum and no oiling is necessary. 

Compared with other tampers the Anchor 
Automatic Tamper is noiseless. All working parts 
are completely housed in permanent steel covers 
and thus kept free from dust. The enclosed work- 
ing parts are all equipped with fiber rollers 
requiring no oil or other attention. The only 
parts requiring oil are the main crankshaft 
bearings. 


Anchor superior construction consisting of 
steel dust-proof tampers equipped with shock 
absorbers, timers and fiber rollers makes this the 
most practical and profitable tamper to operate. 

The Anchor Tamper more than doubles your 
output, and increases the density and uniformity 
of your product. If you are tamping by hand, or 
with an inferior tamper, you are losing money 
every day. Let us show you in figures how much 
you can save by using the Anchor Tamper—the 
tamper of dependable and unequaled performance.

Instructions for Installation and Operation of the 
Anchor Automatic Power Tamper 


For stave tampers hang 
timbers 2 feet 10 inches 
aparl instead of 2 feel 
6 inches as shown 
in sketch 


FRONT VJEW 


Tris drawing shows how the Anchor Automatic 
Tamper is hung. You will note that no floor space 
is required. The timbers on which the Anchor 
Tamper rests can be hung from the ceiling or 
supported by posts placed far enough from the 
machine to be out of the way. Be sure that the 
structure on which the Anchor Tamper rests is 
rigidly braced and does not vibrate excessively. 


Height of Anchor Tamper 


An installation blueprint accompanies each 
tamper. For a side-face machine or stripper 
machine, the tamp feet, when in their lowest 
position, should go into the mold box about 
three inches. 

For face-down machines, the bottom of the 
tamper feet should reach to the bottom of 
the cores. 

For shallow mold boxes using hoppers, such as 
brick machines and silo stave machines, the tamp 
feet should not go into the mold box more than 
one inch. Be sure to hang the Anchor Tamper 
at the proper height. If you find it is too high to 
tamp the blocks properly you can easily raise the 
block machine a trifle or lower the tamper slightly. 


SIDE VIEW 


Speed of Pulley Wheel 


The pulley wheel should run from 75 to 85 revolu- 
tions per minute. Do not run the Anchor Tamper 
too fast. The Anchor Company cannot be re- 
sponsible for breakages in cases where the Anchor 
Tamper is run more than 85 revolutions per 
minute. 

Oiling 

Oil nothing except the crankshaft bearings, 
which are on the outside of the housing. Oil 
placed elsewhere on the Anchor Tamper will 
reach fiber parts and cause them to disintegrate. 
Do not allow the Anchor Tamper to stand out- 
doors or under a leaky roof, as water will also 
ruin the fiber parts. 

Treat your Anchor Tamper properly and it will 
give you good service. Go over it occasionally and 
tighten all nuts, especially the lock nuts on the 
tamp feet. In ordering repair parts, be sure and 
give part number and description as listed on 
page 45. 

If there is anything regarding the installation or 
operation of your Anchor Tamper which you do 
not fully understand, do not hesitate to write us.

The Anchor High-Test Tile Machine 


In these days of high prices anything that will 
reduce the cost of construction is eagerly sought 
by builders. 

That explains why Anchor High-Test Tile is 
the best selling tile made, and why owners of 
Anchor High-Test Tile Machines find their busi- 
ness growing rapidly. 

Anchor High-Test Tile can be manufactured 
at a cost that compares favorably with any other 
type of building unit. But the big saving is in 
the cost of laying. 

Actual tests have shown that a mason in an 
ordinary day’s work will lay three times as much 
wall volume with High-Test Tile as he can lay 
with brick. As a result, the cost of laying a wall 
is substantially reduced, when High-Test Tile is 
used. 

Anchor High-Test Tile gives the builder: 

(a) Low Cost 

(b) Maximum Strength 

(c) Minimum Weight 

(d) Low Moisture Absorption 

(e) Economy in Handling 

(f) Correct Design 

(g) Constant Uniformity 

(h) Wide Adaptability 
Anchor High-Test Tile Machines give you: 

(a) Increased Business 

(b) Growing Profits

High -Test Tile and Stucco 


High-Test tile and stucco make an_ excellent 
form of housing construction, a type universally 
approved. 

The permanent bond obtained, the low moisture 
absorption of the tile, and the smooth wall surface 
secured through the use of the perfectly formed 
units all tend to make an ideal structure that is 
permanent, beautiful and economical to build. 
Stucco, properly applied to. High-Test tile, will 
not crack or peel.

Anchor High-Test Tile Machines Give You 
Advantages of a Wet Mixture 


Tue. design of the High-Test tile with the parti- 
tions extending from top to bottom permits the 
use of a wet, quaky mixture. The strongest con- 
crete will result from using sufficient water to 
produce a stiff, plastic mixture. Such a mixture 
is easily stripped off the High-Test cores, and the 
side walls are smoothly troweled by the sides of 
the mold box. 


This peculiar patented design of High-Test tile 
is also largely responsible for their extraordinary 
strength, and in addition it provides a_ perfect 
handhold for laying the block in the wall. 


Anchor High-Test tile are produced at a re- 
markably low cost because of the simplicity and 
dependability of the Anchor machine. The simple 
and sturdy design of the Anchor machine means 
steady, sure output and freedom from costly delays 
due to breakdowns and adjustments. 


High-Test tile can be made with plain or cor- 
rugated faces. A perfect bond with stucco, 
plaster or mortar is obtained with either face. 


se Anchor High-Test Tile Machine 


is Built for Service 


The Anchor High-Test tilemachine is constructed 
to deliver its product at a profit to the owner. 


Every detail of the construction of these ma- 
chines is the result of long study and experiment 
and no expense has been spared to obtain the best 
of materials and workmanship. 

The result is a reliable, trouble-proof machine, 
that may be depended upon for continuous 
production. The construction is simple and rugged, 
and all parts are guaranteed against defects for 
a period of one year. All machines are given an 
actual running test before shipment. 

Regular equipment provides for the manufac- 
ture of three light weight tile, 5 by 8 by 12. Witha 
slight change in cores and tamps the operator 
can readily fit up the same machine to make 5 by 


4 by 12, 5 by 6 by 8, and 5 by 8 by 10 tile for 
corners, partitions and window and door jambs. 

This modern machine is entirely automatic 
and especially speedy. It eliminates all hand labor 
except the removal of the tile from the machine. 
Three full-size tile or six half-tile are made at 
each operation. 

The Anchor High-Test Tile Machine is not an 
experimental machine. Every High-Test owner is 
a satisfied user. 

Investigation will prove to you that there is 
a sound money-making opportunity in the manu- 
facture of High-Test tile. Let Anchor give you 

figures on what many success- 
ful plants are doing today.

mixture of gypsum and neat cement to insure an even distribution of load. 
The load was applied through a spherical bearing block.

The Walter Conecretile Machine 


Wa Ter Concretile is the roofing material of the 
future. Every day sees the demand for it increas- 
ing. 


The reason is that Walter Concretile is an ideal 
roofing material—fire-proof, storm-proof, and 
water-proof. Besides, it is permanent and it re- 
tains its striking beauty throughout its many 
years of service. 


The increasing tendency is to use tile roofing 
for all kinds of buildings. Its greater permanence 
and moderate price make it practical for the 
modest cottage as well as the most expensive 
home, for public buildings, for garages, barns— 
anything that has a roof. 


Tile manufacturing is a profitable business— 
and the safest, soundest way of building up a tile 
business is to make and sell Walter Concretile. 


With little capital and no experience in tile 
making you can start manufacturing Walter 
Concretile. Anchor service makes sure that your 
tile business will be profitable right from the start. 
If desired, Anchor will furnish an expert demon- 
strator at nominal cost. He teaches your men the 
correct methods of making, handling, curing, 
stacking and laying the tile. If Anchor blueprints 
are followed, the Walter machines can immedi- 
ately be put into operation. 


Big Production at Low Cost 


With the New Improved Portable 
Walter Concretile Machine 


The new improved portable Walter Concretile 
Machine now makes it possible for Concretile 
manufacturers to speed production, cut down 
costs and turn out better tile than with the 
stationary type of machine. 


It’s the only portable tile manufacturing ma- 
chine on the market. It has many exclusive ad- 
vantages that mean easier tile sales with bigger 
profits. 


The portability feature of this machine saves 
thousands of steps daily for each operator. It 
means less waste motion—more time for actual 
production. Steps are saved in two ways—the 
operator moves his machine as the work progresses 
so the tile racks to be filled are always convenient. 


Empty pallets are also always handy. Tile are 
taken off the pallet 24 hours after the tile are 
made and these empty pallets are stacked along- 
side the row of racks. As the machine is moved, 
these stacks of pallets are within easy reach. 


Not only does the operator save thousands of 
steps, but he avoids the energy-sapping work of 
carrying two to three tons of material daily. Figure 
it out—each tile weighs five pounds, pallet seven 
pounds—12 pounds to each time. Each operator 
turns out 400 to 500 tile in a day. 


Think of the heavy carrying avoided in addition 
to time saved, then you will appreciate what 
Anchor has accomplished by building this new, 


52 Anchor Concrete Machinery Co. 


portable Concretile machine. No stationary ma- 
chine can begin to compete with it in output. 

Nor can any other machine produce tile that 
has proved so eminently satisfactory. Portability 
of the machine in itself adds to the quality of the 
product. 

There is less handling of the tile—no shaking, 
jarring, disintegrating of the tile in delivering it 
from the machine to rack. This is bound to happen 
where the newly-made tile is hauled on a truck, 
even though the floor is level and smooth.

Roof tile have been made with these same 
over-all dimensions for hundreds of years in 
other countries. It has always been imprac- 
tical to make pallets or molds for tile of 
greater size. Large pallet molds are too 
heavy and clumsy to handle and they gen- 
erally warp when cast.

Superior Features of the New Walter 
Concretile Pallet 


Note the improved pallet shown here. The non- 
slip cleats are an exclusive, patented Walter feature. 

The cleats grip the concrete and prevent it from 
slipping as the concrete is pressed and worked into 
form with the trowel bar. This gripping action of 
the nonslipping cleats, combined with the high 
compression of the specially designed trowel bar, 
produces a tile of extreme density. Walter Con- 
cretile made on cleated pallets show practically 
no water absorption in use. The result? Tile made 
on these improved, cleated pallets are 18 per cent 
stronger than tile manufactured on the old style, 
smooth-faced pallets. And remember—only Walter 
Pallets are cleated. 


Walter Concretile Roofs Quickly 
and Accurately Laid 

You can positively depend on Concretile to fit 
accurately and lay smoothly. It forms a perfect 
roof, because every tile is uniform in weight and 
dimensions, and warping is absolutely eliminated. 
Concretile has straight edges that interlock ac- 
curately, making a smooth, perfect-fitting joint. 

Two patented “‘buttons’” on pallets mold 
indentations in the tile for nailing tile to the roof 
when necessary. Where these buttons are formed 
the concrete is thin so the nails can easily be 
jabbed through.

The Multiplex Chimney Block Machine 


Tue Multiplex Chimney Block Machine is the 
only one on the market that turns out blocks which 
will make an absolutely fire-proof chimney. 

Advantages of Multiplex blocks are numerous. 
They give the chimney a rounded flue, perfectly 
smooth inside. This gives it a perfect draft so that 
you can burn any kind of soft coal without 
clogging it with creosote. These chimneys never 
need cleaning, because the perfect draft keeps 
them clean. 


The ventilating chambers are outside the 
lining of the flue, and are superheated by the heat 
passing up the chimney. This causes air to pass up 
through the ventilating chambers, and airs the 
house. 

The ventilators, or air shafts, are so constructed 
that registers may be added to the flue, to give 
perfect ventilation and not interfere with the 
smoke draft in the least. 

A small register, say 4 by 8 inches, placed in 
your chimney near the floor, will take all the cold 
and foul air off the floor and keep the floor warm. 
With this system you can warm your house in 
one-half the usual time, and save much fuel.

The Kent Continuous Mixer 


Extremely Heavy Duty Kent No. 3% 


Does the Work Automatically 


Standard No. 2% Kent 


THE Kent Continuous Mixer does every- 
thing automatically. It operates entirely 
by itself. Unlike batch mixers, it requires 
no labor beyond the loading operation. 


Keep the hopper filled with sand and 
cement and the Kent automatically will 
serve your block machine’s charging plat- 
form a continuous stream of perfectly 
mixed and moistened material. 


To keep the hoppers filled, most users 
of Kent machines construct big wood or 
metal bins over the hoppers. With the 
bins filled, the mixer will run on by itself 
for hours, requiring no attention whatso- 
ever. This frees your men for actual 
molding work. 


With wages mounting, the Kent will 
save you money.

The Blystone Batch Mixer 


BiystonE Batch Mixers have been on the mar- 
ket for many years and have given unusual 
satisfaction. 

The cut shows the Blystone Batch Mixer, 
mounted on skids for shop use, in operating 
position; it is in this position that the machine is 
discharged. The mixer is charged while the 
machine is in motion without delay or stopping, 
by use of a platform, 18 to 20 inches high, built 
beside the machine, from which the material can 
be dumped from a wheelbarrow into the mixing 
drum. 

The mixing drum is so carefully constructed and 
accurately balanced that the dumping operation 
is extremely simple, easy to perform and never- 
failing in its action. Three turns of the crank 
handle to the right, and three back, accomplishes 
the dumping and the machine is then ready for 
the next batch. There is nothing connected with 
this dumping arrangement to get out of order, 
and no time is lost in its operation. 

Power discharge device can also be furnished. 
This mixer is made in 7 sizes ranging from 2 to 14 
cubic feet capacity.

Elevators 
Anchor Improved Drag Elevator 


A Dra Elevator is usually more practical in a con- 
crete products plant than any other type of elevator. 

Many drag elevators, however, have disadvan- 
tages which make them objectionable. In Anchor 
Improved Drag Elevator the undesirable features 
heretofore found in this type have been eliminat- 
ed. A study of the illustration reveals an eleva- 
tor which is substantial and practical; one that 
can be applied in almost any plant under any 
conditions. 

Anchor elevators are heavily built. The main 
frames are heavy 3 by 3-inch angles; the bed is 
10-gauge steel. The head and foot equipment is 
extremely sturdy. The chain is No. 62 and the 
cross members are 2 by 2-inch angle. 

The elevator is driven from the head through 
back gears. It may be driven by a chain or belt 
from either the line shaft or other countershaft- 

An important feature of the Anchor elevator is 
that it drags with the top chain—not the bottom 
one, aS is commonly done. This means that in 
feeding the hopper or hood at the foot of the eleva- 
tor it is not necessary to put all the material 
through the moving top chain, thereby scattering 
the material and often clogging the elevator. The 
Anchor elevator never clogs. 

Another desirable feature of the Anchor 
elevator is the fact that the chains never run in or 
through the concrete or material being elevated. 
The chains are always above and outside the 
trough. This is important. 


The standard width of the trough is 16 inches. 
Other widths can be furnished when specified. 
When ordering or asking for quotations always 
give the distance between the centers of the head 
and foot sprockets; specify what size sprocket or 
pulley you wish furnished on the head shaft. 

The Anchor Drag Elevator is a_ simple, 
heavily built machine which is sold at a reason- 
able price.

Quality the Watchword 


By Watiace R. Harris 


President, National Concrete Products Association 
Editor, ‘Concrete Products’? Magazine 


Quauity should be the watchword in every con- 
crete products plant. To overcome competition, 
members of this young but rapidly growing in- 
dustry should realize that the sale of poor prod- 
ucts creates a sales resistance hard to overcome. 

Good equipment must be supplemented by good 
materials and good workmanship. Brains must be 
employed in the concrete industry. Ifa poor prod- 
uct is made, the equipment should not be blamed. 
Investigation will probably show that the trouble 
lies in the aggregate, the lack of water in the con- 
crete mix or in the curing. It is rare that the cement 
is at fault as all cement manufacturers strive to 
maintain a quality higher than the standards set 
for the cement industry. 

Organic matter in the sand is often the trouble- 
some factor. The colorimetric test can be applied 
and the presence of organic matter ascertained. 
In such event it is well to find another source of 
supply. If limestone screenings are used as coarse 
aggregate, fine dust should be eliminated as, in 
some limestones, the flour-like dust is detrimental 
to quality. Pebbles, commonly termed gravel, 
should be free from soft shale or lumps of clay or 
other matter not hard and tough in character. All 
aggregate should be well graded to avoid wasting 
cement. 


The cement content should be in the amount 
required to produce the desired strength, density 
or waterproofness of the products being manu- 
factured. The cement requires a definite quantity 
of water for its crystallization, termed hydration. 
This water should be incorporated in the concrete 
mixture. Curing in a moist, warm atmosphere 
will accelerate the hydration of the cement and 
will result in a stronger product. Cold water 
should not be used as mixing water. It is good 
practice in cold weather to warm the water before 
adding it to the materials in the mixer. It is not 
necessary to use hot water, in fact this should be 
avoided. Water about 100 degrees F. will be suffi- 
ciently warm. 

It is also necessary that aggregate be warmed 
in winter work. It matters not that the machines 
be under cover in a warm room if cold, ice-filled 
aggregate is brought in from the outside. All con- 
crete materials should be warm and thus promote 
the chemical action necessary to result in com- 
plete crystallization of the cement content. 

Steam curing is coming more into use as time 
passes. 

Certificates of Quality are issued by the Con- 
crete Products Association and have been used by 


62 Anchor Concrete Machinery Co. 


operators of concrete products plants to increase 
their sales. To get a Certificate of Quality, it is 
necessary that membership be held in a state 
branch of the Concrete Products Association or in 
the parent body as members at large where state 
branches have not been organized. 

Specimen products are selected by a representa- 
tive of the Association, sealed and shipped by the 
maker to a designated testing laboratory. If the 
products are found to meet the requirements of 
the American Concrete Institute Standards a 
Certificate is issued together with report of tests. 
These have been used effectively to prove that 
quality products are on the market. It should be 
realized that these papers can be used to kill 
malicious propaganda directed against concrete 
products in general. 

Machinery manufacturers are striving to im- 
prove their machines and realize that their 
prosperity depends on the development and pros- 
perity of the concrete products industry. The 
machinery men have donated generously to proj- 


ects designed to promote the best interests of the 
concrete products industry. 

Those entering the industry should realize that 
a reward for honest workmanship awaits them. 
Thought and hard work will, ina properly equipped 
products plant, result in success. 

The building industry is flourishing and will 
continue to boom for many years to come before 
homes equal the ever increasing demand. Those 
selling high-grade concrete building units may 
well feel proud of the part they are playing in the 
construction of durable, sanitary, comfortable and 
beautiful homes sufficient for the humble wage 
earner or for the moneyed man who desires a fire- 
safe mansion. 

The Concrete Products Industry is here to stay 
and pioneers of brains, energy, initiative and 
perseverance will develop with the industry and 
will prosper according to their respective merits. 
The world wants safe homes. The industry can 
furnish the materials necessary for high class 
buildings of any type.
